Filed Aug. 25, 1934 Patented Nov. 10, 1936 UNITED STATES CONNECTER Leland H. Hill, Wauwatosa, Wls., assignor to Allis-Chalmers Manufacturing Company, Milwaukee, Wis., a corporation of Delaware Application August 25, 1934, Serial No. 741,418

2 Claims.

This invention relates generally to connecters for removably connecting one conductor to others and particularly to connecters wherein one conductor is removably fastened to the connecter by means of a screw thread or is permanently fastened to the conductor by sweating or soldering, and the other conductor or conductors are removably fastened to the connecter by clamping means.

It is an object of this invention to provide a novel and improved connecter of the above type, wherein the size of the connecter is greatly reduced while at the same time the connecter is stronger and more rugged.

It is a further object of this invention to provide a connecter in which the body of the connecter is more efficiently related to the clamping means physically, electrically and mechanically.

Another object of the present invention is to provide a connecter of the above type, when used in an abutting relation to a supporting member, with a clamping means so related to the body of the connecter as to greatly reduce 26 the extent of the connecter from the supporting member.

These and other objects and advantages are attained by this invention, various novel features of which will be apparent from the disclosure and drawing herein and will be more particularly pointed out in the claims.

An illustrative example of an application 01' this invention is shown in the accompanying drawing, in which:

Figure 1 is a sectional view of the assembled connecter taken on the line II of Fig. 2;

Fig. 2 is an end view of the connecter as shown in Fig. 1;

Fig. 3 is'a bottom view of the connecter.

The connecter has a body member I which has a flange H on one end which provides an enlarged fiat surface capable of forming an abutting support for the connecter assembly. 45 The body member 1 has a longitudinal opening 9 which, as shown, may be threaded to receive therein a threaded portion of the shank 20 of a conducting stud member 5. The stud 5 is arranged to receive a conductor l3 therein which 50 is fastened thereto in a suitable manner as by sweating or soldering. In the bottom of the body member 1 is a longitudinal groove 8 adapted to receive a conductor II which is clamped to the body member I by a U-shaped bolt l6 and saddle member IS. The bolt IS straddles both the groove 8 and the opening 9 and is adjusted into clamping relation by the nuts I'I.

Upon assembling the connecter the stud 5 which has been connected to a conductor l3 by sweating or soldering is inserted through an opening in a casing 4 through an insulating bushing member 6. If the casing is non-conducting the members 6 and I4 may be omitted. An insulating gasket I4 is then placed in posi- 10 tion and the connecter screwed on to the stud 5, the flange II tightly clamping the stud member in position and rigidly supporting the same on the casing 4. The conductor I2 is then inserted in the groove 8 and the U-bolt adjusted 15 to clamping relation by the nuts II.

By arranging the groove 8 in overlapping relation to the longitudinal opening 9, the extent of the connecter from the casing 4 is very materially reduced. This makes the connecter more rugged and avoids breakage due to any strain that may be applied by the conductor l2 or due to an accidental blow delivered to the connecter itself. This feature is of especial importance where the connecter is the only member extending from the casing 4 as, for example, where the casing 4 is a transformer casing and connecters such as shown form the secondary terminals thereof. Also due to the overlapping relation of the two conducting members less material is necessary between them and hence a shorter electrical path is provided and the size of the connecter is materially reduced without reducing mechanical strength.

Although only one embodiment of the present 35 invention has been illustrated and described, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims.

It is claimed and desired to secure by Letters Patent:

1. In combination, a casing provided with an aperture therein, a conducting stud provided with a shoulder in abutting relation to one side of said casing and having a screw threaded portion extending through said aperture, a connecter provided with a body member having an opening therein adapted to receive said screw threaded portion of said stud member, a flanged portion on said body member in abutting relation to the other side of said casing, a groove in the outer surface of said body member adapted to receive an additional conductor therein in overlapping relation to said opening and means for clamping said additional condustor to said body member, said means including a member provided with portions extending through said body member and straddling said opening and said groove. 7

2. In a device of the character described, a casing provided with an insulated aperture therein. means for clamping a connecter in said aperture comprising a conducting stud member provided with a shoulder in abutting relation to one side oi said casing and provided with a screw threaded portion extending through said aperture, said means further comprising a body member of said oonnecter having a flanged portion in abutting relation to the other side of said casing and iurther provided with an opening in said body member adapted to receive said screw threaded portion of said stud member, means for clamping an additional oonductor to said body member, said means comprising a groove in the outer surface of said body member overlappingly adjacent said opening and said last said means further comprising a U-bolt provided with portions extending through said body member and straddling said opening and said groove.
